1. Foundational Commercial Coverages for Ontario Enterprises
Whether operating a retail storefront in Toronto, a manufacturing facility in Cambridge, or an engineering consultancy in Ottawa, Ontario commercial operations face distinct liability and asset risks. Independent RIBO brokers structure commercial package policies (CPPs) combining essential protections:
Commercial General Liability (CGL)
Covers third-party bodily injury, property damage, and personal and advertising injury occurring on your business premises or resulting from ongoing work. Standard limits range from $2,000,000 to $5,000,000.
Commercial Property & Equipment
Insures commercial buildings, leasehold improvements, tools, inventory, office furnishings, and machinery against insured perils such as fire, water damage, windstorm, vandalism, and theft.
Business Interruption / Extra Expense
Replaces lost business operating income and pays ongoing fixed expenses (payroll, rent, debt service) during forced closures caused by direct physical damage from an insured peril.
Errors & Omissions (E&O) / Professional Liability
Protects professional advisors, consultants, technology developers, and engineers against financial loss claims arising from alleged negligence, errors, or failure to deliver services.
2. Ontario Specific Mandates: WSIB and Municipal Certificates
Operating an enterprise in Ontario involves interfacing with specific provincial and municipal standards:
- Workplace Safety and Insurance Board (WSIB): Most construction, manufacturing, and transportation firms must register with WSIB for workplace injury coverage. Note that WSIB covers worker injuries; it does NOT protect against third-party lawsuits, requiring private CGL.
- Municipal Licensing Requirements: Municipalities like the City of Toronto, Mississauga, and Ottawa require verified Certificates of Insurance naming the municipality as an additional insured before granting trade permits or street occupancy approvals.
- Commercial Leases: Standard Ontario commercial lease covenants mandate tenants carry a minimum of $2M to $5M CGL and property coverage on leasehold improvements.
